Cuestions about the Returns Transfer Orders for Expense Items

In the 24C update of Oracle Cloud, an improvement was added regarding the Returns Transfer Orders for Expense Items functionality (Functionality that did not exist before).
I am doing some tests to be able to carry out the functionality and implement it in the business operation.

But I would like to see if you can resolve my two doubts:

1) When I generate a Return Transfer Order through the Return Receipts task (Standard Screen), the Return Transfer Orders shows "Not Applicable" at the line level. Is any configuration necessary?

2) When I confirm the order from the Shipment Lines screen, the lines remain in Shipped status, they do not remain in Interfaced as the Returns Transfer Orders of Inventoriable Items do.
